This is just a small example of the MIS information floating around about foreskins, and it's what makes forums like this SO important!
You might also hear stories of boys/men who "had" to be circ'ed later; how having a foreskin predisposes a boy to all sorts of dread diseases, including UTIs, penile cancer, and HIV; how a penis with a foreskin is difficult to keep clean, and therefore can be rank and smelly.
The truth is that foreskins on little boys are SUPPOSED to be tight, to prevent ooky stuff from coming in contact with the glans, and into the urethra. In fact, at borth the foreskin is literally fused to the glans, with an opening just big for urine to pass through. As long as the child CAN pass urine, the opening is big enough. Gradually, the foreskin separates, a little at a time. This can happen during the toddler years, or the foreskin might not fully retract until puberty. There is no exact timetable - any more than there is an exact time when girls should develop breasts.
Unfortunately, in a society where circumcision is the norm, even doctors are vulnerable to the myth and misinformation. And because circumcision is the norm, they often are not experienced at treating males with foreskins, and many choose circumcision as the treatment of chjoice for anything that might go wrong with the penis.
In countries where circumcision is only performed for religious reasons, and most of the males have foreskins, there is rarely a need for later circumcisions. Infections are treated with antibiotics, actual cases of phimosis (tight foreskin) are treated with a steroid cream - NOT surgery.
The foreskin is a perfectly normal, healthy part of the body, and no more likely to have problems than any other part. As a wise parent, you will monitor your child's health, and seek medical attention for ANY part of his that has problems - there's no need to cut bits off to prevent possible problems in the future! And as a compassionate paretn, you will make sure that your child's treatment for any medical problem will start with the least invasive treatment, leaving surgery as a last resort after other treatment has failed.
Welcome to the board, and best wishes to you for a comfortable pregnancy and a healthy baby!
